Can artificial intelligence classify textual records?
AI can categorize documents very accurately.  It is not a new application but in the last year the accuracy of the underlying algorithms such as text classifiers, and language models in general, has significantly improved.  There are applications of language models which now surpass human performance. Microsoft is one of the leaders in this area.  For example, see their Turing Natural Language Generation (T-NLG) language model: Turing-NLG: A 17-billion-parameter language model by Microsoft. The T-NLG was developed in a research group called Project Turing which works on AI tools for Microsoft's products including Office-365.  My guess is this same research group makes the AI for Project Cortex.
